General Site Preparation Guidelines Facility Characteristics Floor Loading Terms Table 2-2 Floor Loading Term Definitions Term Dead load Live load Concentrated load Ultimate load Rolling load Average floor load Definition The weight of the raised panel floor system, including the understructure. Expressed in lb/ft2 (kg/m2). The load that the floor system can safely support. Expressed in lb/ft2 (kg/m2). The load that a floor panel can support on a 1-in2 (6.45 cm2) area at the panel's weakest point (typically the center of the panel), without the surface of the panel deflecting more than a predetermined amount. The maximum load (per floor panel) that the floor system can support without failure. Failure expressed by floor panel(s) breaking or bending. Ultimate load is usually stated as load per floor panel. The load a floor panel can support (without failure) when a wheel of specified diameter and width is rolled across the panel. Computed by dividing total equipment weight by the area of its footprint. This value is expressed in lb/ft2 (kg/m2). Average Floor Loading The average floor load value is not appropriate for addressing raised floor ratings at the floor grid spacing level. However, it is useful for determining floor loading at the building level, such as the area of solid floor or span of raised floor tiles covered by the hp Integrity rx5670 footprint. Typical Raised Floor Site This section contains an example of a computer room raised floor system that is satisfactory for the installation of an hp Integrity rx5670. Based on specific information provided by HP, Tate Access Floors has approved its Series 800 all-steel access floor with bolt-together stringers and 24 in. (61.0 cm) by 24 in. (61.0 cm) floor panels. In the event that the flooring is being replaced or a new floor is being installed, Tate Access Floors recommends its Series 1250 all-steel access floor with bolt-together stringers and 24 in. (61.0 cm) by 24 in. (61.0 cm) floor panels be used to support the HP installation. NOTE If the specific floor being evaluated or considered is other than a Tate Series 800 floor, the specific floor manufacturer must be contacted to evaluate the floor being used. The following table lists specifications for the Tate Access Floors Series 800 raised floor system.
